ELECTRIC-LIGHT FIXTURE.

To all whom it may concern:

Be it known that I, RICHARD S. GIESE, a citizen of the United States,residing at Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented anew and useful Electric-Light Fixture, ofwhlch the following is a specification. I

This invention has reference to electric light fixtures and its objectis to provlde a combination semi-indirect and shower fixture in whichmetallic parts are reduced to a minimum. I

In accordance with the present invention there is provided a dish orbowl of the general character employed in semi-indirect lighting butmodified in structure to adapt it to the purposes of the presentinvention, and such bowl is utilized as a spreader for the shower lightswhile the shower devices are employed as the supporting means for thedish or bowl.

employed to sustain the dish or bowl of the semi-indirect side of thefixture are avoided, and the only metallic parts employed are thecustomary sockets for the lighting bulbs of the shower, chains carryingthe bulbs, and

the customary shade-holders supporting' shades such as are. used inconnection with single lamp bulbs, such shades forming the sole supportfor the dish or bowl.

The invention will be best understood from a consideration of .thefollowing detailed description, taken in connection with theaccompanying drawings forming part of this specification, with thefurther understanding that while the drawings show a practical form ofthe invention, the latter is not confined to any strict conformity withI the showing of the drawings, but may be shown ordinary electric lampsockets 1 de- In this manner all me-- tallic rings or other supportscustomarily Specification of Letters Patent.

having shade-engaging set screws 4.

In shower lights it is customary to employ elongated shades quiteclosely surrounding the lamp bulbs, andsuch shades are indicated 1n thedrawing at 5. Each shade is provided with a neck 6, which where joiningthe body of the shade forms a shoulder 7. Each socket 1 is provided witha suspension ring 8 which may be of standard or special constructionandarranged for the passage of the usual conductor 9 and the reception of asuspension chain 10 of the character ordinarily employed 1n electriclight fixtures.

'The chains 10 in the installed fixtures are carried to a ceiling canopyand there secured in the customary manner, but as this is the commonpractice in the installation of shower and other lighting fixtures, itis not deemed necessary to show it.

Shower electric lighting fixtures are often provided with a spreader forthe shower lights in the form of a plate or dish of ornamentalconfiguration, which dish is suspended by chains, such as the chains 10,while sockets, such as sockets 1, are installed in the dish or plate toreceive the bulb, such sockets belng sometimes suspended from the dishor plate by short chains.

By the present invention there is provided a dish or bowl 11 of glass orother suitable material usually of a translucent nature, that is, theglass or other material is of a character to transmit light difl'usivelywhile the inner wall of the dish is made reflecting for the purpose ofdirecting light against the ceiling of the room or compartment in whichthe fixture is installed. This is the usual practice in semi-indirectlighting, and with the fixture of the present invention there isprovided a lamp socket 12 designed to carry an electric light bulb 13,the socket being suspended by a customary conductor cord 14 dependingfrom the usual canopy supporting the fixture, but which canopy is notshown in the drawings.

The dish or bowl 11 has its rounded or generally convex face directeddownwardly,

so that the hollow interior of the dish is toward the ceiling and at theelevation at which the fixture is usually placed the bowl I 20 for thedish 11 completely hides the lamp bulb 13 from observation. The dish 11has upstanding sides 15 usually provided at the upper edge with a flange16 serving as an ornamental finish.

The central portion of the dish has a drop i necks 6 of the shades 5through them with the portions of the dish immediately surrounding thepassages 16 resting on the shoulders 7. These shades, therefore, serveas supports and consitute the sole supports At the same time thedisposition of the passages 19 is such that the dish 11 serves as aspreader for the direct lighting elements of the shower. The result isthat the sole supporting means for the en- I tire fixture consists ofthe chains 10 each of which carries a socket 1 individual thereto, andthese chains are the only metallic parts needed for the suspension ofthe entire fixture from the usual ceiling canopy, (not i shown).

The bulge 17, which extends downwardly in the installed position of thefixture, is designed to partly house the lamp bulb 13, so that thesource of indirect lighting represented by the bulb 13 is partly withinthe bulge 17, thus increasing the light transmitted through the dishtoward the floor of the compartment to be illuminated, while reflectionsfrom the inner surface of the dish toward the ceiling cause the lightingup of 00 ture may be used either as a direct fixture or as asemi-indirect fixture, or the two styles of lighting may be employed atone time.

By the present invention the benefits of both direct and semi-indirectlighting are r obtained with a minimum of metal in the fixture, and withthe elimination of more or less unsightly and shadow-casting parts.

The fixture also has the advantage of economical construction, forcertain parts i such as the sockets 1, heretofore employed in suchfixtures solely to carry the direct light 7 ing members, are utilized inthe present fixture as, the supporting means for the indirect lightingside of the fixture, that is, the

' 6 dish 11.

The shower lights are shown in the drawings as three in number, but itwill be understood that any suitable number of such lights may beemployed, and usually such lights are distributed evenly about thefixture.

lVhat is claimed is 1. An electric light fixture provided with showerlights each having supporting means individual thereto, and asemi-indirect lighting dish or bowl carried directly and solely 7 by theshower lights.

2. An electric light fixture comprising a plurality of electric lampsockets and suspension devices therefor, shades for the sockets, and asemi-indirect lighting dish having passages therethrough for the shadesand resting 011 and supported solely by said shades.

3. An electric light fixture comprising a plurality of electric lampsockets, shades and shade holders therefor, suspension means connectedto the sockets, and a semi-indirect lighting dish having passagestherethrough for the necks of the shades and resting upon and supportedby the shades, said dish serving as a spreader'for the sockets andshades to constitute-the fixture a combined shower and semi-indirectfixture.

4. An electric light fixture provided with a plurality of electric lampsockets, shades and shade holders therefor, suspension means connectedto the sockets, and a semiindirect lighting dish having upstandingsides, a central hollow depression, and substantially flat portionsbetween the central depression and the sides, said fiat portion havingpassages therethrough distributed about it for the necks of the shades,the dish resting upon and being supported by the shades, whereby thefixture constitutes a combined shower and semi-indirect lightingfixture.

5. In an electric light fixture of the com- 'bined shower andsemi-indirect type, a semi- ;1I1d1160l3 lightlng dlsh having upstandlngmarginal portions, a central hollow depression, and a substantially fiatportion surrounding the hollow depression and merging into theupstanding sides, the fiat portion having passages therethroughdistributed circumferentially about the central depression.

6. A combined shower and semi-indirect electric light fixture,comprising a semi-indirect dish or bowl, and shower lights extendingthrough and below the bowl and provided with supporting means, theshower lights constituting the sole support for the dish. 7 a

7 An electric light fixture provided with shower lights each havingsuspension means connected and individual thereto and con stituting thesole suspension means for the entire fixture, and aspreader fortheshower lights and the suspension means, comprising a semi-indirectlighting dish or bowl directly engaging and carried solely by the showerlights.

8. A combined direct and semi-indirect lighting fixture provided withseparate direct lighting means, a separate suspension means for eachdirect lighting means a spreader for the separate direct lighting means,comprising a semi-indirect lighting dish or bowl directly engaging thedirect lighting means, and means for supporting light producing means inoperative relation to the dish or bowl to direct light through the bowland for the reflection of light from 15 the bowl to produce indirectlighting effects;

9. A combined direct and semi-indirect lighting fixture comprising asemi-indirect dish or bowl, and a series of separate shower lightsextending through and below the bowl within the margins thereof and eachprovided with a suspension means individual thereto, the bowlconstituting a spreader for the suspension means and said suspensionmeans constituting the supporting means for the fixture.

In testimony, that I claim the foregoing as my own, I have heretoailixed my signature in the presence of two witnesses.
